Abstract: The present utility model provides a loudspeaker box. A sound-producing monomer divides an accommodating space into a front cavity and a rear cavity. A baffle wall divides the rear cavity into a first rear cavity and a second rear cavity. A lower cover comprises a lower cover body, a protruding wall, a second through hole and a cover plate, wherein the lower cover body and the protruding wall jointly enclose a sound guide groove which is communicated with the second rear cavity. The first rear cavity communicates with the sound guide groove by means of the second through hole. The cover plate completely covers the second through hole. A second air-permeable spacer is attached to the protruding wall and completely covers the sound guide groove. The second rear cavity is filled with sound-absorbing particles, and a first air-permeable spacer and the second air-permeable spacer jointly encapsulate the sound-absorbing particles in the second rear cavity to form a virtual sound cavity. A part of the airflow in the second rear cavity enters the first rear cavity through the first air-permeable spacer, and the other part of the airflow bypasses the baffle wall and sequentially passes through the second air-permeable spacer, the sound guide groove and the second through hole to enter the first rear cavity. Compared with the prior art, the loudspeaker box provided by the present utility model is excellent in low-frequency acoustic performance.
